PARALOID™ Impact Modifiers for EV Battery Casings
Due to government investment and rising consumer demand, electric vehicles are primed for exponential growth. With the passage of the bipartisan Inflation Reduction Act, numerous provisions pertaining to electric vehicles and EV charging infrastructure will accelerate the adoption of this alternative energy source. The Build Back Better plan features include substantial incentives for passenger electric vehicles, such as tax benefits and the ability to reassure consumers with respect to drivers’ range anxiety.
The federal government has currently approved 35 state proposals for an EV charging infrastructure spanning 53,000 miles of highway. Safety, compliance, performance, and cost are significant factors in the ultimate acceptance of e-mobility. Traditional metal components encounter cost, weight, and general design constraints when creating EV battery packs, casings, or enclosures.
Due to their favorable qualities, engineering resins and composites (or blends) are increasingly utilized in automotive under-the-hood applications. The thermoplastic applications for both internal combustion engine automobiles and electric vehicles will greatly increase. EV battery case makers prefer flame-resistant polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) mixes due to their modularity, interoperability, and second-life use by recycling battery enclosures.
EV Battery Enclosures
Lightweighting is essential for EV manufacturers to improve overall efficiency and driving range. The U.S. Environmental Protection Agency (EPA) estimates a 1%–2% improvement in fuel efficiency for every 100 lb of vehicle weight loss or reduction. For under-the-hood lightweighting, various composite materials must encase the lithium-ion batteries that power the vehicle. Composite battery enclosures or casings must withstand the structural needs of these electric motors, but they can also lower the vehicle's weight by substituting traditional metal components.
Battery enclosures for EVs, PHEVs, and HEVs are the housing and frame of the battery engine and they protect the battery cells. Thermal management and impact strength are critical for protection against thermal runaways.
